Total number of coins that Yoko and Irene shared = 100%
If Yoko gave 117 coins to Irene, both would have the same number of coins.
Number of coins that each would have in the end
= 100% ÷ 2
= 50%
Number of coins that Yoko gave to Irene
= 63% - 50%
= 13%
13% → 117
1% → 117 ÷ 13 = 9
Number of coins that Irene had
= 37%
= 37 x 9
= 333
Answer(s): 333
